1. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
Correct answer: C
Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
2. Nursing care plans are _______________?
- A. written by CNAs before they provide care
- B. guidelines of care that all nursing team members use
- C. used by nurses but not by nursing assistants
- D. used by nursing assistants but not by nurses
Correct answer: B
Rationale: Nursing care plans are comprehensive documents created by registered nurses to outline individualized care for patients. These plans serve as guidelines for all members of the nursing team, including nursing assistants, to ensure consistent and quality care. Choice A is incorrect as CNAs typically assist in implementing the care plan rather than creating it. Choice C is incorrect as nursing care plans are utilized by all members of the nursing team, not exclusive to only nurses. Choice D is incorrect as nursing assistants also utilize nursing care plans to provide patient care effectively.
3. Which of the following is a disadvantage of using a dry heat application?
- A. Dry heat is more likely to cause burns than moist heat
- B. Dry heat does not penetrate deeply into the tissues
- C. Dry heat causes the skin to dry out more quickly
- D. Dry heat can quickly cause skin breakdown
Correct answer: C
Rationale: The correct answer is that dry heat causes the skin to dry out more quickly. When comparing dry and moist heat applications, dry heat is less likely to cause burns and skin breakdown. However, one of the disadvantages of dry heat is that it does not penetrate deeply into the tissues and may lead to faster drying out of the skin. This can have negative effects on skin integrity and overall comfort during therapy. Choice A is incorrect because dry heat is less likely to cause burns than moist heat. Choice B is incorrect as dry heat may not penetrate deeply into tissues. Choice D is incorrect as dry heat is less likely to cause skin breakdown compared to moist heat.
4. During auscultation of a patient's heart sounds, the nurse hears an unfamiliar sound. Which action would the nurse take?
- A. Ask the patient how he or she is feeling.
- B. Document the findings in the patient's record.
- C. Wait 10 minutes and auscultate the sound again.
- D. Ask another nurse to double-check the finding.
Correct answer: D
Rationale: When encountering an unfamiliar sound during auscultation, it is crucial for the nurse to seek confirmation from another healthcare professional. Asking the patient about their feelings may not provide insight into the unfamiliar sound. Simply documenting the findings without verification may lead to errors in interpretation. Waiting and auscultating again after 10 minutes might delay necessary intervention. Consulting another nurse for a second opinion ensures accurate identification of the unfamiliar sound and appropriate follow-up actions.
5. What is the purpose of MSDS sheets?
- A. Contain the ordering information for each piece of equipment in the office.
- B. Are required by OSHA to be accessible to all employees of the office.
- C. Can be used to treat patients who have been injured in equipment accidents.
- D. None of the above.
Correct answer: B
Rationale: MSDS sheets, also known as Materials Safety Data Sheets, are essential documents that provide detailed information about chemicals used in the workplace. They are required by OSHA to be easily accessible to all employees to ensure they have the necessary information to handle chemicals safely. MSDS sheets do not contain ordering information for equipment in the office (Choice A) or serve as a treatment guide for injured patients (Choice C). Therefore, the correct answer is that MSDS sheets are required by OSHA to be accessible to all employees of the office.
